According to the i.MX 7Solo/Dual Application Processor Reference
Manual the ECSPI1/2/3, UART1/2/3 and SAI1/2/3 peripherals are
connected through the SPBA bus. Other similar SoCs such as i.MX 6UL
add this bus abstraction. This adds the bus also to the i.MX 7
device tree.

The i.MX SDMA driver uses this abstraction to configure watermark
levels slightly differently, so this might change behavior slightly.
There have no issues been observed before or after the patch.

This is a rebased version of patch [0].

The 32 kHz reference clock on the i.MX6UL(L) can be output by
setting the external signal XTALOSC_REF_CLK_32K in one of the
following ways [1]:

|----------------------------------------------------------|
| Signal              | Pad             | Mode | Direction |
|----------------------------------------------------------|
| XTALOSC_REF_CLK_32K | ENET1_RX_EN     | ALT2 | O         |
|                     | GPIO1_IO03      | ALT3 |           |
|                     | JTAG_TCK        | ALT6 |           |
|----------------------------------------------------------|

Before patch [2] the mux mode for the external reference clock was
missing. The patch named the mux mode as used in the NXP Linux
4.9.11_1.0.0 release, but the Reference Manual uses the name
OSC32K_32K_OUT, e.g. in [3].

As Philipp and Shawn suggest the name from the RM should be used
instead.

The eSDHC does not work properly if the SION bit is not set for the
bidirectional CMD signal, whatever the eSDHC instance and the selected
pad. Therefore, setting SION is mandatory for all eSDHC CMD ports. Do
this for MX25_PAD_*__ESDHCn_CMD in imx25-pinfunc.h in order to enforce
this behavior for all boards.

This had already been done for eSDHC1, but not for eSDHC2. Also, define
MX25_PAD_FEC_MDC__ESDHC2_CMD so that all the possible cases are covered
from now on.

This file had several naming inconsistencies for eSDHC:
 - the instances were named sometimes SDn, sometimes SDHCn, whereas they
   are named ESDHCn in the reference manual, e.g.:
     MX25_PAD_SD1_CMD__SD1_CMD
     MX25_PAD_D15__SDHC1_DAT7
 - the data ports were named sometimes DATAn, sometimes DATn like in the
   reference manual, e.g.:
     MX25_PAD_SD1_DATA0__SD1_DATA0
     MX25_PAD_D15__SDHC1_DAT7
 - in one case, the clock port was named DAT_CLK instead of CLK:
     MX25_PAD_CSI_D7__SDHC2_DAT_CLK

This change:
 - introduces new definitions using the naming from the reference
   manual,
 - keeps definitions using the legacy naming in order not to break
   compatibility for out-of-tree users (they can be removed later),
 - updates the in-tree files that were using the legacy naming.
